Hello,
I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it.
First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly. The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference. My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation.
The code to render the image is the following:
Dim para As Paragraph = New Paragraph
para.Alignment = Image.RIGHT_ALIGN
para.Add(text)
Dim imageFile As String = String.Format("{0}{1}", GetAppSetting("UploadDirectory"), myCompany.LogoUrl)
Dim thisImage As Image = Image.GetInstance(imageFile)
thisImage.Alignment = Image.LEFT_ALIGN
para.Add(thisImage)
The printed images are the following:
Image printed directly with iTextSharp
Image edited and printed with Acrobat 8
Please let me know if I need to provide more info. Thanks
